intercom to CCTV

Hi,

I have an intercom system in my house. A box on the wall outside with a speaker and a button, and inside a phone handset.

I want to upgrade to something with a camera.

Does anybody know if the wiring for an audio handset system like I have can be reused with a video one or would I need to put in extra wiring?

Thanks.

It really depend on what cable is used for the audio handset.

Most digital audio systems will only use 2 or 3 cores but with a video a bit of screening on the cable helps to get a clearer picture inside.

Can you open your handset or the call station and see what wire is inside it.
